I googled for this but I couldn't find the answer. If I am allocated (or choose) an exit row seat does this effectively rule me out of the op-up pool? Seems like once a QF staffer confirmed that I am suitable for an exit row seat that upgrading me for operational reasons may be difficult?
I was op-upped at the gate on QF9 MEL-SIN from my exit row seat to Premium Economy. So doesn't seem to rule you out.
